Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a shut-off valve with flow regulation function. Background Technology

[0002] Gate valves, also known as stop valves, are the most widely used type of valve. They are popular because of the low friction between the sealing surfaces during opening and closing, making them durable. They also have a small opening height, are easy to manufacture, and are convenient to maintain. They are suitable not only for medium and low pressure but also for high pressure.

[0003] Traditional gate valves are mainly used to cut off or connect the flow of media in pipelines. However, in actual industrial production and civil applications, it is often necessary to precisely regulate the flow rate of fluids to meet the needs of different working conditions. Existing gate valves can usually only achieve the function of being fully open or fully closed. Although some gate valves have a certain flow regulation capability, the regulation accuracy is low and it is difficult to meet the requirements of high flow control. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a shut-off valve with flow regulation function, which has the advantage of freely controlling the flow rate and solves the problem of low regulation accuracy of traditional shut-off valves.

[0005] To achieve the aforementioned objective of freely controllable flow rate, this utility model provides the following technical solution: a shut-off valve with flow rate regulation function, comprising a shut-off valve body, wherein a fluid channel is provided inside the shut-off valve body, one end of which is an inlet and the other end is an outlet, connecting pieces are provided on the left and right outer walls of the shut-off valve body, a valve body is provided on the top of the shut-off valve body, and an adjustment component extending into the fluid channel is provided on the valve body, wherein a flow rate regulation mechanism is provided at one end of the adjustment component extending into the fluid channel;

[0006] The flow regulating mechanism includes a guide block and a sealing gasket. The top of the guide block is connected to one end of the regulating component that extends into the fluid channel. The bottom of the sealing gasket is connected to the inner bottom wall of the fluid channel. A main flow channel is provided at the bottom of the guide block. Three branch flow channels are provided at the left end of the guide block, and the right ends of the three branch flow channels are all connected to the main flow channel. Three leak-proof rings are provided on the outer wall of the guide block.

[0007] Furthermore, the guide block is cylindrical in shape, and the sealing gasket has a circular groove that matches the guide block.

[0008] Furthermore, the three anti-leakage rings are located above the three branch channels, and the outer wall of each anti-leakage ring is in contact with the inner wall of the shut-off valve body.

[0009] Furthermore, the adjustment assembly includes a threaded sleeve, a threaded rod, a handwheel, a bearing, a valve core, and a limiting guide rod. The threaded sleeve is fixedly inserted through the top wall of the valve body. The threaded rod is internally threaded and connected to the threaded sleeve. A handwheel is provided at the top of the threaded rod. The bottom of the threaded rod is fixedly connected to the top of the valve core through a bearing. Two limiting guide rods extending into the valve core are fixedly installed on the inner top wall of the valve body.

[0010] Furthermore, the bottom of the valve core is connected to the top of the guide block, and the connection between the two is a fixed connection.

[0013] 1. This shut-off valve with flow regulation function, through the setting of a flow regulation mechanism, firstly, when the guide block separates from the sealing gasket, the inlet water flow will flow into three branch channels through the main channel at the bottom of the guide block. Then, the guide block can expose the three branch channels in sequence according to its own rising height. The three branch channels correspond to three flow velocities. At this time, the operator can freely select the three flow velocities as needed.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 In this embodiment, a shut-off valve with flow regulation function includes a shut-off valve body 1. The shut-off valve body 1 has a fluid channel inside, with one end being an inlet 101 and the other end being an outlet 102. Connecting pieces 2 are provided on the left and right outer walls of the shut-off valve body 1. A valve body 3 is provided on the top of the shut-off valve body 1. An adjustment component 4 extending into the fluid channel is provided on the valve body 3. A flow regulation mechanism 5 is provided at one end of the adjustment component 4 extending into the fluid channel.

[0020] The flow regulating mechanism 5 includes a guide block 501 and a sealing gasket 502. The top of the guide block 501 is connected to one end of the regulating component 4 that extends into the fluid channel. The bottom of the sealing gasket 502 is connected to the inner bottom wall of the fluid channel. The guide block 501 is cylindrical in shape. The sealing gasket 502 has a circular slot that matches the guide block 501. The bottom of the guide block 501 has a main flow channel 503. The left side of the guide block 501 has three branch channels 504, and the right side of each of the three branch channels 504 is connected to the main flow channel 503. The outer wall of the guide block 501 is provided with three anti-leakage rings 505. Three anti-leak rings 505 are located above the three branch channels 504, and the outer wall of each anti-leak ring 505 is in contact with the inner wall of the gate valve body 1. Therefore, when the guide block 501 separates from the sealing gasket 502, the water flow from the inlet 101 will flow into the three branch channels 504 through the main flow channel 503 at the bottom of the guide block 501. Then, the guide block 501 can expose the three branch channels 504 in sequence according to its rising height. The three branch channels 504 correspond to three flow rates. At this time, the operator can freely select the three flow rates as needed. Finally, by setting the anti-leak rings 505 above each branch channel 504, the water in the branch channel 504 can escape effectively. Thus, this design can not only effectively control the flow rate of the water, but also effectively ensure the sealing environment inside the gate valve body 1. It is very practical.

[0021] In the implementation case, the regulating component 4 includes a threaded sleeve 401, a threaded rod 402, a handwheel 403, a bearing 404, a valve core 405, and a limiting guide rod 406. The threaded sleeve 401 is fixedly inserted into the top wall of the valve body 3. The threaded rod 402 is threadedly connected to the inside of the threaded sleeve 401. A handwheel 403 is located at the top of the threaded rod 402. The bottom of the threaded rod 402 is fixedly connected to the top of the valve core 405 via a bearing 404. The bottom of the valve core 405 is connected to the top of the guide block 501, and the connection between the two is fixed. Two limiting guide rods 406 extending into the valve core 405 are fixedly installed on the inner top wall of the valve body 3. Simultaneously, the valve core 405... The valve core (405) has two insertion holes that are adapted to the limit guide rod 406. The inner wall of the insertion hole and the outer wall of the limit guide rod 406 are in a sliding connection relationship. The limit guide rod (406) can ensure that the valve core (405) can only move in the vertical direction and avoid rotational deviation. Then, the handwheel 403 is rotated first, so that the threaded rod 402 and the threaded sleeve 401 can rotate and move at the same time through their threaded connection relationship. Then, while the threaded rod 402 rotates and moves, the design of the bearing 404 and the guide limit rod 406 makes the valve core 405 move up and down stably. This design can effectively ensure the stable mechanical movement of the valve core 405 and facilitate subsequent flow control work.

[0022] In the implementation of the case, a waterproof sealing gasket 6 is provided on the outer wall of the valve core 405. The outer wall of the waterproof sealing gasket 6 is in contact with the inner wall of the valve body 3. This design can effectively prevent water from escaping from the valve body 1.

[0023] In the case implementation, both the sealing gasket 502 and the anti-leakage ring 505 are made of elastic rubber material. The outer diameter of the anti-leakage ring 505 is slightly larger than the inner diameter of the gate valve body 1. Dynamic sealing is achieved through interference fit. At the same time, the material has strong deformability and can effectively fill gaps and spaces to achieve a sealed environment.

[0024] When implementing this procedure, please follow these steps:

[0025] 1) First, when the guide block 501 separates from the sealing gasket 502, the water flow from the inlet 101 will flow into the three branch channels 504 through the main channel 503 at the bottom of the guide block 501.

[0026] 2) Then the guide block 501 can expose the three branch channels 504 in sequence according to its rising height. The three branch channels 504 correspond to three flow rates. At this time, the staff can freely select the three flow rates as needed.

[0027] 3) Finally, by setting a leak-proof ring 505 above each branch channel 504, water in the branch channel 504 can be effectively prevented from escaping.

[0028] In summary, this flow-regulating gate valve, through the flow-regulating mechanism 5, allows the water flow from the inlet 101 to first separate from the sealing gasket 502 when the guide block 501 separates. The water then flows through the main flow channel 503 at the bottom of the guide block 501 and into three branch channels 504. The guide block 501 then exposes the three branch channels 504 sequentially based on its rising height, corresponding to three flow rates. Operators can freely select the three flow rates as needed. Finally, by installing a leak-proof ring 505 above each branch channel 504, water escapes from the branch channel 504. This design effectively controls the water flow rate, and the leak-proof ring 505 also ensures a tight seal inside the gate valve body 1. It is highly practical and solves the problem that existing gate valves typically only achieve fully open or fully closed functions. While some gate valves have some flow regulation capability, their regulation accuracy is low, making them unsuitable for applications with high flow control requirements.
